Abstract
Methods and systems are provided for intelligent call routing through distributed VoIP networks. A host name, representing a proxy, is assigned to and associated with a device. An IP address of a first proxy is acquired via a DNS query for the host name. The quality of the connection between the first proxy and the device is measured at least in part by calculating the round-trip delay for messages between the first proxy and the device. A DNS record for the host name is changed to specify the IP address of a second proxy. The IP address of the second proxy is acquired via a second DNS query for the host name. The quality of the connection between the second proxy and the device is measured at least in part by calculating the round-trip delay for messages between the second proxy and the device. The quality of the first and second connections is compared, and the IP address of the proxy with the higher-quality connection is assigned to the DNS record.
